Home extensions in Long Eaton
We design and build extensions, loft conversions and garden rooms for homes in Long Eaton and the NG10 area, from single storey rear extensions on terraces to larger double storey and wrap around projects.
Long Eaton has a Nottingham postcode but sits in Derbyshire, so planning goes to Erewash Borough Council rather than a Nottinghamshire council. We work on both sides of the border and set out the approvals your project needs at a free survey.
- Free site survey anywhere in NG10

Why the council matters in Long Eaton
People are often surprised that an NG10 address isn’t in Nottinghamshire. Long Eaton, including Sawley and Wilsthorpe, is in the Borough of Erewash in Derbyshire. Erewash Borough Council decides planning applications, prior approval requests and Lawful Development Certificates for your home.
Being in Derbyshire also means the county council for highways is Derbyshire County Council. That matters if your project needs a new dropped kerb for a driveway, or a skip or scaffolding on the road outside, because those permits come from the highway authority rather than the borough.
The border runs close by. Toton, next door, is in Broxtowe in Nottinghamshire, so two homes a short walk apart can go through different councils. We confirm the right authority for your address before any application is made.
Who handles what
- Planning: Erewash Borough Council
- Building Regulations: local authority building control or a registered approver
- Highways, dropped kerbs, skips on the road: Derbyshire County Council
Areas we cover
Long Eaton town centre, Sawley, Wilsthorpe and the wider NG10 area. Not sure about your street? Ask and we will confirm.
Two approvals, two different questions
Planning permission asks whether the extension is acceptable in its setting: its size, appearance and effect on neighbours. Building Regulations approval asks whether it is built properly: structure, foundations, insulation, drainage, ventilation and fire safety. A project can need one, both, or occasionally neither, but almost every extension needs Building Regulations approval.
For Building Regulations you can apply to local authority building control or appoint a registered building control approver, which is the current term for what used to be called an approved inspector. Either inspects the work as it goes and issues a completion certificate. Keep that certificate safe, because a buyer’s solicitor will ask for it when you sell.
Matching the extension to the house
Older terraces near the town centre often have narrow rear yards. Here a single storey rear extension or a side return extension can turn a small kitchen into a usable kitchen diner without taking the whole yard. These sites are tight, and building near the shared wall usually means serving notice under the Party Wall etc. Act 1996.
Interwar semis often have room at the side for a side extension or a two storey addition. Newer homes towards the edges of town can suit wrap around extensions and double storey extensions, subject to plot size and any planning conditions on the estate.
Permitted development: the national limits
- Single storey rear: up to 3m deep on a terrace or semi, 4m detached, 4m high
- Side: single storey, up to 4m high and no wider than half the original house
- Two storey rear: up to 3m deep and not within 7m of the rear boundary
- Not available in the same way in conservation areas or where rights have been removed
Your property needs to be checked. These limits have further conditions, and we confirm the position at the survey.

Long Eaton extension questions
Derbyshire. It has Nottingham (NG10) postcodes, but it is in the Borough of Erewash, so planning goes to Erewash Borough Council and highways matters go to Derbyshire County Council.
Yes. We cover Long Eaton and nearby Nottinghamshire areas such as Beeston and Stapleford. The drawings and approvals follow the same national rules; what changes is which council receives them.
Not always. A single storey rear extension up to 3m deep may fall under permitted development, depending on the property and any restrictions. Deeper extensions can go through prior approval or a planning application to Erewash. We check which applies at the survey.
Often, on terraces and semis. Building on or near a shared wall, or digging foundations close to a neighbour’s, usually needs notice under the Party Wall etc. Act 1996. If your project goes through prior approval or a planning application, the council will also consult neighbours.
Derbyshire County Council, as the highway authority. A skip or scaffold on the pavement or road needs a permit, which is usually arranged by whoever supplies it. We plan this into the programme.
As an indicative guide, single storey rear extensions start around £40,000 and double storey builds from about £70,000. Size and specification decide the real figure, which comes as a written, itemised quotation after a free survey.
Typically 10 to 14 weeks on site once approvals are in place. Design, planning and Building Regulations come first and are separate stages. Double storey and wrap around projects take longer, and we give you a schedule with your quotation.
Nearby, on the Nottinghamshire side
Beeston and Stapleford are both in Broxtowe Borough Council’s area.
